I started PT after a car accident. The staff was extremely helpful not just with injuries from the accident, but also other issues that had been bothering me. They are very good at communicating problems and solutions and are friendly to boot. Can’t recommend enough.

Attentive, responsive, pleasant in communication, knowledgeable staff. I got good results in a short time. Thankful to Dr. Andrew for useful information and for a program of exercises.

Doug Free, the manager at Mercer Island Physical Therapy, has a PhD in PT, and is an amazing diagnostic doctor who explains why a specific injury occurred. He also does fabulous work on your body. His entire staff is knowledgeable and excellent therapists.

I saw Anne at 7 weeks post ulnar nerve transposition. I’ve made more progress in 1 week with her than I did in those first 7. She is extremely knowledgeable and up to date on current research. I’d feel very good about sending my family and friends her way!

Kelly is amazing! I felt very comfortable and she asked all of the right questions, was super friendly, and knows exactly how to help. I always leave feeling so much better, and confident that if I do my exercises, I will heal!

Michelle has been amazing to work with. She quickly diagnosed the root cause of the issues that continued to plague me after recovering from hip replacement surgery that other PT’s (different companies) could not. She listens, is creative, resourceful, and very knowledgeable. Everyone at the clinic is always very professional and interested in our progress.

I have been going to Summit Therapy for a shoulder problem. I’ve made steady progress and have gotten much pain relief. The staff is very friendly and great to work with. I recently had a sudden problem of vertigo. My therapist knew exactly what to do and performed a treatment that stopped the dizziness.
